Specification of Letters Patent.

Patented.Feb. 19,1907.

Application filed October 4, 1905- Renewed November 12, 1906. Serial No.343,118.

To all whom it may concern:

' Be it known that I, ADRIAN C. KINTNER, a citizen of the United States,residing at Cumberland, in the county of Allegany and State ofMaryland,have invented a new and useful Improvement in Eyeglasses, ofwhichtionary lenses and may as readily be removed whendesired.

The device of my invention is so constructed as not to detract from thelooks of the glasses nor interfere with the sight,' either when theremovable lenses are in position or when not in use, and is alsoconstructed in such a manner as to hold the removable lenses securely inposition when'in use.

Other features of my invention will be fully set forth in the followingspecification and pointed out in the claims.

Inthe accompanying draWinggFigure 1 is a perspective view of a pair ofeyeglasses hav-. ing my inlrention applied thereto, the smoked lensesbeing held in the position they occupy when in use. Figfiis a frontview. Fig. 3

is a detailed view oi' the bracket for supporting the removable lenses.

Referring to the accompanying drawin s, forming part. of thisspecification, and in which like numerals of reference designate likeparts, 1 designates the stationary lens, 2 the smoked or removablelenses, and 3 the bracket for supporting-the removable lenses.

The glasses are provided with the usual mountings, comprising a spring4, nose-pieces 5, and studs 6, to which the stationai y lenses aresecured.

I Thebrackets 3 have their inner'ends? bent downwardly and provided withapert lies 8 and are held to the studs 6 by means-of screws 9, passingthrough said apertures 8 into the said studs. Th' outer enfl of ,thesaid bracket is bent at light angles and extends a short distance infront of the station ary lenses and is parallel therewith The said outerend of the braeket'is bifurcated, the upper prong 10/ of which isprovided with a pivot 11, on which the-removablelens2 swings, and thelower prong 12 is bent outwardly and then inwardly to form a pocket or'seat for the removable lens when held in position. The lower prong 12is bent back sutiiciently far to cause the inner surfaces of the saidseat to impinge against the opposite sides of the removable lens when inposition and hold it friction-tight.

' While I have shown the bracket 3 with a bifurcated outer end, it is.obvious it may be solid or constructed in any suitable manner,

so long as itis provided with a pivot and a seat in close proximity tothe said pivot.

To place the smoked or removable lenses in position, they are firstplaced on the pivot 11 and then moved downwardly until they rest in theseats 12, where they will be securely hold, both by their weight and bythe friction of the inner surfaces of the seats, as hereinbeforedescribed.

To remove the lenses 2, they are simply swung up on their pivots 11sufficiently far to free them from their seats 12 and then lifted fromsaid pivots.

Having thus described my invention, What I claim is l. The combinationwith the eyeglasses comprising the usual mountings and the stationarylenses, of the removable lenses, and a bracket havingone end secured tothe said mountings and provided with a pivot on which the removablelenses'swing and a seat below the pivot and adapted to suspend theremovable lenses in front of the stationary lenses.

, 2. The combination with the eyeglasses comprising the usual-mountingsandthe stationary lenses, of the removable lenses, a bracket having itsinner end attachedto the eyeglasses and its outer end bifurcated andprojecting in front of the stationary lenses, the upper prong of thebifurcated end being provided with a pivot on which the removable lensswingsand the lower prong being provided with a seat in which theremovable ens rests when in position. 1

3. The combination with theeyeglasses comprising the usual mountingsandthe stationary lenses, of the removable lenses, and the brackets secured,to the said mountings and-having a pivot on which the said removablelenses swing and a seat inclose proximity to said pivot, said seat beingadapted to hold the lenses friction-tight when seated.

4. The combination with the eyeglasses having the usual mountingscomprising a end the brackets each having one end secured spring,the-nose-pieees, and the stud.s,-end the In testimonywhereof I'hwesigned my stationary lenses, of the removable lenses, name to thisspecification in the presence of I f d d d h l tWo subscribingWitnesses.-
